WILLIM KLIIVIAS, OF PATERSON, NEW JERSEY.

COMBINATION-LOCK.

Application filed April 13, 1917.

To all whom it may concern Be it known that I, WILLIM KLIMAs, a subject of the Czar of Russia, resident of Paterson, county of Passaic, and State of New Jersey, have invented certain new and useful Improvements in Combination-Locks, of which the following is a specification.

This invention relates to improvements in locks, particularly to types adapted to be used with containers having a hinged cover.

The principal object of the invention is toprovide a. lock partaking of permutative character and having combined additional securing features.

A further object is to provide a lock com prised of few and simple parts, not readily liable to become disordered and which are relatively inexpensive to construct.

These and other like objects are attained by the novel construction and combination of parts hereinafter described and shown in the accompanying drawings, forming a material part of this specification, and in which Figure 1 is a perspective view showing the application of the lock to a container.

Fig. 2 is an enlarged vertical sectional view taken substantially on the center line of the same.

Fig. 3 is a front plan view of the lock, parts being broken away to show the interior construction.

Fig. 4 is a rear plan view of the same.

Fig. 5 is a perspective view, looking from the lower side of the principal operating member, and

Fig. 6 is a perspective view showing one of the details of construction.

In the drawings, the lower or body portion of the container is indicated by the numeral 10, and the upper cover element 11.

Attached to the body 10 is a plate 14, its upper edge being formed into one element of a hinge 15 with which is engaged a tongue 16 in such manner that the same may be turned or folded outward when released.

Rigidly engaged with the extreme outer end of the tongue 16 is a bar 18 turned outwardly and forming a hook 19 substantially parallel with the tongue 16, the same being receivable within an opening formed in the cover element 11 of the container.

In this cover is formed an opening receptive at its inner side of a plate 20, the same being rigidly secured by screws 21 or other like fasteners.

Specification of Letters Patent.

Patented Aug. 14, 1917.

Serial No. 161,733.

Also rotatably mounted within the opening 23 is a disk 25 having a flanged base 26 abutting against the plate 20, a portion eX- tending outwardly through the wall of the container and having upon its upper surface a series of graduations 24.

Mounted on the outer surface of the disk 25 is a knob 28 having a knurled periphery 29, the outer face of the knob having a series of numerals 30 by which its position relative to the numerals 24 may be ad justed.

A stem 32, rigid with the knob 28, extends through openings centrally formed in the disk 25 and plate 20, where it is upset or riveted forming a head 33 preventing it from being withdrawn but permitting the knob to be freely turned.

A bracket 35 is secured to the inner side of the plate 20 and carries a lever 36 pivoted by the pin 37 in the bracket, the longer end of the lever being held normally downward by means of the pull spring 38.

Attached to the shorter end of the lever 36 is a rod 39, its upper end being engaged with a plunger 40 freely slidable in an opening 41 formed in the container, the exterior of the plunger 40 having the same general appearance as the dummy rivets 42 set in the top of the container.

Attached to the longer arm of the lever 36 is a rod 44, the same passing through an opening 45 in the plate and having its upper end engaged with the plunger 46 slidable in an opening 47 formed in the disk 25, the plunger being of a length equivalent to the thickness of the disk.

Registerable with the opening 47 in the disk 25 is a similar recess 50, formed in the knob 28, in such manner that the plunger 46 may be engaged therein by pressure applied upon the knob 40, the plunger 46 normally being pressed downwardly out of engagement with the recess by means of the spring 52 contained therein.

The hook 19 is normally engaged by the flange 26, in which is a single radial slot 54, so formed that when the disk 25 is rotated to a determined point the hook 19 may pass through the slot, thereby freeing the lock hook from engagement.

In operation, the dial 28 may be rotated until certain ofthe numerals on its face register with other numerals displayed upon the face of the disk 25 whereupon the knob 40 is depressed raising the plunger 46 partially into the recess 5 0 thereby engaging the disk with the knob which may be further rotated until the slot 54; registers with the hook 19 whereupon the lock may be opened in the usual manner, or locked as desired, the hook 19 being held by the lower surface of the flange 26 immediately upon turning the same through the connecting plunger 46.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a clock of the class described, the combination with a hinged tongue having a rigid hook element at its free end, of a disk having a single radial recess in its periphery, a plunger movable in said disk, a knob rotatably engaged with said disk, said knob having an opening alinable with the plunger in said disk, means for moving said plunger into engagement with said knob, and means for rotating said knob into a predetermined position.

2. In a lock of the class described, the combination with a hinged tongue having a hook element at its free end, of a plate, a rotatable disk adjacent to said plate, a knob rotatably mounted on said disk and plate, said disk and knob having registerable openings, a plunger normally contained in the opening in said disk, a lever for operating said plunger, and a depressible knob for actuating said lever whereby said knob and disk may be engaged and rotated to bring the mentioned. slot into alinement with the hook on said tongue.

In testimony whereof I have aflixed my signature.

WILLIM KLIMAS.
